    PowerBook 140 Display Blue

    Just checked the inverter board and found some More caps. Pics of screen caps also attached

    PowerBook 140 Display Blue

    Oh, ok. I will have to look into making a file for that sometime or other. Thanks for telling me about the logic board, I wasn't sure if it was the same case as my 170 that also only has tantalums. I don't remember seeing caps on the inverter board, but I will check that later today as well.

    PowerBook 140 Display Blue

    I'll provide some pictures later today, It didn't look like too much leakage, but hopefully its not inside the cables. Only 3 or 4 out of 11 seemed to be leaking, but I would imagine that all are long dead. Edit: I am missing one of the hinge cover pieces, do you know if they have 3d printable...

    PowerBook 140 Display Blue

    I just got given a PowerBook 140, and it seems to work other than the display. It is in pieces for standoff replacements, but is put together enough to test. I hear chime and drive activity, but the display stays blue regardless of contrast slider. Brightness is only on or off, no dimming at...

    PowerBook 170 Battery

    This is some of the info from the other thread, there is an stl file in the other thread which I may print tonight and test tolerances on my printer since its been a little bit weird recently. I have some AA batteries lying around to fit in, but they wont be used in the final result. These seem...

    PowerBook 170 Battery

    I think I will just purchase a small spot welder since I plan to buy more PowerBooks, and there is a person local to me who would be able to benefit from working batteries as well. This is definitely going to be a long project, but I cant wait to have a working battery eventually. Guy I knew...

    PowerBook 170 Battery

    Alright, thanks again. I don't need amazing battery life, maybe just an hour or two, so I will look into the AA cells.

    PowerBook 170 Battery

    Where should I start with rebuilding the battery? I can 3d print parts if necessary, but since my battery isn't swelling or leaking, it should be possible to reuse the shell. Where would I buy the cells, and what cells should I use? I have a standard temperature adjustable soldering iron and...

    PowerBook 170 Battery

    Well, of course it ended up doing basically nothing, so I will have to re-cell it eventually. That will be a fun project to tackle.

    PowerBook 170 Battery

    Alright. Just making sure :) I never knew about the non-removeable faceplates, so that's new to me, thanks for correcting me.

    Thanks much!

    PowerBook 170 Battery

    If you didn't know, you can take the sliding part off the battery, just be very careful. That is what I have done so I don't have a hole in it. Thanks for the file though as I will certainly use it in future.

    PowerBook 170 Battery

    Thanks. I may be able to find a printable case for a shell if I need, I recall seeing some in the past.

    PowerBook 170 Battery

    Well, should be a fun little experiment anyways. Where would I even find any reconditioning software? At worst, nothing improves, so its worth a shot. On a side note, is it worth re-celling since its in good condition, and what would that require in terms of tools and materials? I have a 3d...

    PowerBook 170 Battery

    I have a PowerBook 170 that is in great physical condition. The only thing wrong with it apart from pretty bad tunnel vision is the battery. The battery does charge and increases voltage, but is not powerful enough to turn on the laptop. When using a multimeter, the voltage of the cell is...

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    I was thinking calipers were a good option but that would probably be better. That's good that its typical! At least its repairable then.

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    Oh I noticed that in my 170 but thought it would be different in the 540. That could cause a large problem in trying to change it Would you be able to send some more pictures from different angles? I will have to disassemble my 170 again to see if there is a way to remove the film. I didn't...

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    $100 for that is really good for one of those! My 170 has a non leaking battery as well but I have no idea how to rebuild that unfortunately. You should be able to order the diffuser film all over the place from sites like alibaba, though I don't have any experience with them and don't know if...

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    That sucks. Those 540s seem to be relatively expensive even when dead. I wonder if you could put something like a piece of paper in between to see if it helps remove the yellowing. If you can measure the thickness of the diffuser, you should be able to replace it with a new sheet of the same...

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    I haven’t seen anything like that before... Looks like liquid but there aren’t any other traces. The best option is to replace it. There may be a way to cover it up with something but I can’t think of a good way to make the entire screen an even color. I wonder if you can just put any diffuser...
